Application March 14,

7 Claims.

My invention relates to window ventilators and more particularly to the type built into or forming a part of sash portion of the window.

One object of the invention is to provide a simple and inexpensive construction which is easy to install, and which provides for adequate ventilation of a room while preventing entrance of rain and Wind.

Another object is to provide a ventilator which is easy to manufacture, neat in appearance, and built into the bottom of a window sash so as to occupy no more space than the rordinary sash portion of a window.

A further object is to provide simple and eilicient means for controlling the admission of air 'to the room through the Ventilator.

Various other objects and advantages of the invention will be apparent as the description proceeds, and as illustrated in the accompanying drawing forming a part of this specification, and in Which:-

Fig. 1 is an outside or weather side of a window equipped with my improved ventilator,

Fig. 2 a view of the window showing the inside or room side of the ventilator construction,

Fig. 3 a cross-section on the line 3-3 of Fig. 2, and,

Fig. 4 a detail adjacent the bottom of the window sash.

In the drawing II) indicates a window frame in which a sash II is mounted to slide, so that the window may be opened or closed in the usual Way. I have combined Ventilating features in the bottom portion I2 of the sash so that the window may occupy a normally closed position and be latched in the usual way as a protective measure to prevent unauthorized raising of the window sash.

It will be noted that the bottom of the Window sash is provided with a series of openings I3 extending through the sash from the weather side I4 to the interior or room side I5 for the passage of air. Preferably the openings I3 are inclined upward from the weather side I4 as at I6 to aid in excluding rain which otherwise may be driven directly across the openings. Much of the rain which strikes the bottom surfaces of the openings I3 will drain from these inclined faces to the outside of the sash. Furthermore, I provide screens I1 which may be held in place over the openings I3 and against a' recessed portion between the front and rear walls I9 and 20 of the sash as at I 8. A plate 2| having apertures 22 opposite the openings I3 provides simple and effective 1936, serial No. 68,805

means for holding the screens in place. Fasteners such as screws 23 may be used for securing the plate over the screens and to the body of the sash. For controlling the admission of air to the room or for shutting off the supply entirely there is provided a door 24 which is swingably connected at 25 to the bottom portion of the sash I2. The sash is recessed as at 26 to receive the door 24 in its closed position against the openings I3, and a gasket or frame of felt or other suitable material 21 effects a tight joint against the door surface when the door is held closed by suitable means such as latch pieces 28 engaging over catch elements 29 attached to the free outer edge of the door. A handle or knob 30 may be provided for facilitating closing and opening of the door. The door may be held in various angular positions by means of an adjustable brace 3l so as to control and direct ther ,c

means of a thumb screw 34, the other end of,

the link 33 being pivotally secured to a stationary bracket 35 mounted in a recess 36 in the sash between a pair of the openings I3.

Beneath the screens I1 there is a channel portion 31 formed in the body of the sash and which is adapted to catch drainage from the screens resulting from moisture or `rain being driven thereagainst. The channel portion 31 extends across the sash beneath the entire series of openings I3, and has an exit or drainage port 38. Moisture or rain which may be driven through or 01T of the screens toward the interior of the room, as by a high wind, will fall onto the inclined upper surface of the door, which may be readily adjusted for the particular weather prevailing at the time, and will drain toward the channel portion 31 and over a deflector or bridge piece 4G extending the length of the door adjacent the hinged part of the door and then into the channel. It will be seen that the deilector also protects the hinged connection 25 of the door from moisture which may drain from the screens. When the door is fully closed as in Fig. 4 the deector it projects down into the channel portion 31 and provides the same protection at the bottom of the door.

It is to be understood that the invention as abo-ve described is not confined to the exact details of construction set forth, but is capable of being embodied in various other modied forms lof construction or variously altered within the scope of theappended claims. This includes any suitable form of metal construction or combinations of metal and wood or other materials utilizing the fundamental principles set forth in this specication.

Having thus described my invention, I claim:
